BOX LIN ING MACHINE 1930. Serial No. 468,103.

A further purpose is to taper off the end lugs of a box locator for more easy entry of the box to the space between the lugs and to extend the lug on the advancing side of the box further inward than the lug on the rearward side thereof to permit the lug that is at said advancing side to overlapand stop the box at the moment a push rod pro-' gressing' the box forwardly from a loading station to a charging station comes to rest. .7

A further purpose is to firmly clamp a box to a definite position during the liningoperation by locator members that hold the box tom of'the box, that thereafter expands the bottom lining into the bottom corners of the box and then turns the side flaps outwardlyabout the bottom corner edges into firm engagement with the interior of the'box sides.

A further purpose is to provide mechanism 7 adapted to closely fit the lining intothebottom corners of a box. V

A further purpose is to provide mechanism for applying an extension of a back flap over the hinge of a box lid in order to reinforce the hinge after placing the lining upon the bottom and sides of the box. I

A further'purpose is to provide a roller that is to be used in turning a reinforcement flap from a box lining over the hinge of the 7 box lid with desirable guide mechanism. A further purposeis to provide a roller that rolls areinforcement flap on to the back of a box and on to thelid, mounting the roller upon a member carrying a right angle cushion for pressingthe flap to place upon the corner.

Further purposes will-appear in the specification and in the claims.

I have elected'to illustrate one only of' the many different forms of my invention, se-

lecting a form that is practical and efficient in operation and Which well illustrates the principles involved.

Describing in illustration and not in limitation and referring to the drawings My semi-automatic box lining machine inserts into cigar boxes or the like cruciformshaped lining blanks of paper,-which have been previously suitably glued, preferably stencil gluedin any suitable way, by any standard gluing machine, such as a Stokes & Smith, at present in use for gluing wrap on paper boxes.

;I have indicated. diagrammatically any suitable gluing machine25 having starting mechanism 26 operatively connected to the starting treadle of the lining machine so that theglue machine and lining machine operate anism, not shown.

in synchronization, indicating a wrap 27 on the glue machine carrying a stencil coating of glue 27.

I connect the clutch mechanism of the stencil gluer to a treadle 28 (Figure 1) of my lining machine in such a manner as to release the glue machine for one cycle of operation each time a box is lined by my lining machine.

With th s exceptlon, no connection need 'exlst between the two machines, and'since the stencil gluing machine is well known in the artof covering paper boxes, it is believed neither necessary nor desirable to show it nor to describe it in greater detail.

As best seen in Figures 1 to 3 the illus trated embodiment ofmy invention includes a supporting framework 31 which carries a three station track 32, the different operations of the machine taking place sequentially at the loadlng station 33, the lining station 34 and the reinforcing station 35, oper-.

ations at the latter station however being omitted if the back fiapof the lining is not to be extended up over the edge of the lid to reinforce the hinge. 1

An operator places a box 36 and a lining blank 27 from the glue machine in the posi-,

tion 37 glue side down, in vertical registry at the loading station 33 and depresses the,

treadle 28 which through intermediate lever -mechanism 29 and starting rod 26'. operates,

the clutch 30 to cause rotation of main cam shaft 40 through'suitable belt and gearing 39. It also normally operates the glue machine to deliver glued blanks as needed.

The track 32 provides a horizontal straight guideway for the boxes, each ofwhich is,

placed on the guideway at the feeding station 33, its lining blank placed on the top of the open box between the arms of a movable gauge 41, the blank registering vertically above the open. box and the box, blank and gauge being then progressed as a unit to position beneath a form 42. 1,

When the box, blank and gauge have come to rest, the form 42 moves down between spaced arms of the gauge 41 into the box applying the lining to the box, then moves up out of theway the carrier and transfer mechanism returning to the feeding station for another box and'blank and the lined box being progressed forwardly from beneath the form during the advance of the next box the lid for hinge reinforcement or, where thisfeature is not desired, discharging the lined box to a suitable conveyor or piling mech- An essential feature of my box lining machine includes the vertically reciprocating form 42 which carries the lining downward-j ly'i'nto' the box, and then expands outwardly against the box sides, pressing the lining into place. v

. lid.

Other features include means I for feeding both the box and thelining into positiym' beneath the form, for locating both the box and the lining in a predetermined position a there, and for expelling the lined box.

I may or may not extend the lining up to reinforce the lid hinge and my machine'includes mechanism for accomplishing thisthat is not used when the reinforcementfeature 10 is not desired. I

An operator picks up a gluedlining blank 29 with one hand and an unlined box 36 with the other and inserts the box on to the track 32 at the feeding station 33with the rearward end of the box against the forward side of an upwardly projectinglug 43 of the box transfer mechanism;

As soon as the box is in place the operator drops the cruciform lining blank on top of it between upwardly extending arms of the paper gauges 41, the lining blank, glue side down, being then supported on'three sides by the box edges, and on the fourth sideby a stationary-bar 44 that is optionally omitted if there be not a box lid. This bar functions to prevent the downwardly directed gluedsurface of the fourth side of the lining from engaging and adhering'to the inside ofthe The bar 44 may be supported in any suitable way, not shown, from the stationary structure, as from a bracket in front of the first or feedposition of the box, or from any bracket at the side or front out of the path of travel of thebox lid and locating the rod a little above'the line'of travel of the lid.

When both the box and its lining blank are in proper position at the feeding station, the machine is started for one complete cycle of operation. The gluer is also started at the same time. H a

The box, lining and g'auge advance along the track to the/lining station 34-beneath the form, where the box is stopped and'held by l-ocators 45, the lining blank still being held in registry with the open box the paper gauges 41.

The form 42'w1th parts'contracted, d e scends into the box. carryingthe lining blank down against the box bottom, and causing the four wings or flaps 46, 47, 48 and 49 of the lining blank to stand upright inside the box adjacent the vertical box walls.

The function of the paper gauges"has been fulfilled at the lining station as soon as the lining blank is carried downwardly clear of the gauges and the gauges return to the feeding station, to 'permit'the insertionand location of the next box and lining,

even before the form has completed the lining of the first box. I r j 1 The'four sides of the box-form are provided with plates 50 which expand-at their bottom edges into the bottom corners'of the" box after the body of the lining has been pressed down to thebottom of the box.

. Thiscarries' the paper outwardly into the four bottom corners of the box creasing the paper into the bottom corners.

Immediately afterwards, the upper edges 7 of the four plates 50 move outwardly, con1- pressing outwardly directed sponge ILlbbeli pads 51 along the upper edges of the plates against the box sides, through the paper new and unlined box is being advanced from the feeding. station to the lnnng stat1on,as

described above.

After the lined box has come to rest at the reinforcing station, an upwardly projecting reinforcing flap 53 ofv the lining is turned over on to the edge of the lid 55 by a small roller 54, the flap 53 immediately thereafter being firmly pressed into place by a right angle shaped sponge rubber pad 56.

The lined and reinforced box remains standing at the reinforcing station until the beginning of the third cycle of operation, when it is expelled from the machine at the end of the track;

The track 32, best seen in Figures 1, 2, 3 and 17 to 20 consists of along rectangular casting 57 mounted upon the frame structure 31-, with guides 58 and 59 along the .sides, the

boxes being slid along the top of the track from station tostation between the guides.

" The upwardly directed surface of the track is level for the full lengthlof the track along the sides at 60 and 61 except for recesses that seat brackets 62 that support the guides 58 and 59. i

The top surface of-the track is closed between side runway portions 60 and 61 for about two thirds of the track length, with the exceptionof a central slot opening 63that passes the transfer lugs 43, 43 and 43 to engage the boxfends. f w

Thecasting 57 is left open intermediate the runway portions 60 and 61 at the reinforcing station since no strain is given the box bottoms during the reinforcing operation,and except for the slot 63 closed at the lining station to support the downward thrust of the form, and also closed, except for the slot63, at the feeding station, where an open track would make insertion of the boxes less easy. I

Three lugs 43, 43 and 43 respectively ad vance the boxes from the feeding station 33 tion 34 to the reinforcing station 35, and

from the reinforcing station 35 off the end ofthe track.

The three lugs '43, 48. and 43 are adjust-V ably mounted on a rectangular bar 64, (F igures 8, 9 and 19) which reciprocates horizontally in a sleeve 65.

The sleeve is provided with two downwardly projecting slides 66 which vertically reciprocate in two bearings 67. 7

Horizontal reciprocation of the bar 64 is effected by a stud 68 which extends downwardly from the lower side of the bar through a suitableslot in the bottom of the sleeve 65 to engagement with a forked projection 70 of a horizontal slide 71 (Figure 1) the details of which will be explained later.

7 Vertical reciprocation of the bar 64 is obtained by the movement of the sleeve 65 driven up and down by the levers 72 attached to the rocker shaft'7 3.

- The downwardly extending slides 66 from;

the sleeve 65 carry small studs 74 which engage the rocker levers 72 in suitable slots.

The rocker 72- toward the discharge side of the machine-carries an operating arm 72" in operative connection with a connecting rod 75, a lever 76,-(Figure 1) and a cam 77 located on the cam shaft 40.

The lugs 43, 43' and 43 are carried for-. ward by the bar 64 while in their raised position each lug pushing a box ahead of it along the track.

When the bar 64 has reached the end of its forward stroke, each lug has advanced its box one station, and the bar and lugs then descend far enough for the lugs to clear the box bottoms, the bar then retracting to its initial position where it rises presenting the lugs in their previous stations in position to advance the next boxes.

While on thetrack, the boxes are guided laterally by the two side members 58 and 59 one of which extends the full length ofthe track, the other extending only the length of the lining and reinforcing stations, being cut off at the feeding station 33 to permit mor easy entry of the boxes. 7

l The side guides 58 and 59 are adjustably mounted on the casting 57 by means of'the angle brackets 62, the horizontal'parts of which are recessed into the casting and slotted in a direction transverse to the track to pass the screws 78, this arrangement permitting lateral adjustment ofjthe side railsato suit the width of the box intended to be lined.

- The side guides 58 and 59 are set to allow.

one pair at the lining station 34 and one pair at the reinforcing station 35.

The box locators 45 are suitably of cast brass, with the distance between the projecting lugs 79 and 80 governed bythe length of the box for which they are intended to be used.

7 with an assurance of an exact registry of the new locators with respect to the lining form,j

reinforcing mechanism, etc'., without further ad ustment.

I provide means for preventing the boxes when advancing from one station to another from continuing to move, after the box trans-- fer mechanism 43, 43 and 43 comes to rest, that is from running past the proper station and do this by continuing the lugs 80 at the. ends of the locators 45 farthest away fromv the feed station to extend inwardly beyond the inward ends of the lugs 7 9 at the locator;

ends nearer thefeed station. 7

The locators 45 being to closetoward the box before the latter has quite reached its station, the inward extensions of the lugs 80 forming a positive stop for the-box, while the shorter lugs 79 permit the box to move to its proper station at which point the transfer lugs 43, 43 and 43 come to rest. I

The inward extensions of the lugs 80 keep the boxes from travelling onward after the transfer lugs 43, 43 and 43 come to rest. If the lugs 79 were as long as the lugs 80, the lugs 79 nearer the feed station would gouge the front and back of the box by their premature closing. 7 V i,

The locators completely close and clamp the box just as the box has fully reached its position in thestation.

V The castings 8l to which the locators are fixed, close and open to'the same limits regardless of the dimensions of the box to 'be lined, such differences in box dimensions be ing taken care of by corresponding differencesin the dimensions of the locators.

For narrow boxes, the locators are made correspondingly thicker at the point 82 and for wide ,boxes they are correspondingly thinner. I v

Whenthe locators are completely closed, they should clamp the box between them because any variance in box'location would I prefer touse a separate set of locators for are fixed ontwo rock shafts 83, mounted in suitable bearings 84 which are secured to the outer sides of the casting 57.

The two castings 81 toward the discharge 1 side of the machine are eachprovided with an inwardlyprojecting arm 85:5(Figure 17),

these arms passing inwardly through the sides of the casting 57 in slots for that purpose.

Two short connecting rods 86, ad ustable in length, extend from these levers to the slide 87 which is vertically movable and in a stationary vertical guide 88, Figure 1, downwardly directed from the table casting.

A connecting rod 89 extends from the bottom of the slide 87 to a lever 90 which is driven by a cam 91 on the main cam shaft.

\ The paper gauges and lining locating mechanism, Figures 1 to 3 and 14 to 16 are important features.

I; The linings are located under the head mechanism independent of thebox locating means. i 7

Boxes of various sizes can always be locatedunder the head properly by the-means described above, but devices for adjustment of the linin blank location are necessar due to varying conditions in the paper itself, as well as to possible differences in the cutting of the cruciform lining blanks,

I show threepaper gauges 92, 93' and 94 for registering in'three of the four corners of the cruciform blanks, each adapted to engage one side of each wing adjacent the corner. I have found it unnecessary, and from the standpoint of quick adjustments, undesirable, -to use'a paper gauge at the fourth c'o'rnerof the lining blank.

The two paper gauges 92 and 93 at the receiving end of the track are adjustably mounted on a horizontal non-circular bar 95, Figures 14 to 16, which is rigidly held in a lateral arm from'a hinged head 96 of a holder 97 that is adjustably mounted on a horizontal transverse bar 98.

The head 96 pivots horizontally at 99 on the forward end of the holder 97, being adapted to be swung on its pivot in either direction away from its normal position by rearwardly deflecting a spring plunger 100 that normally holds the head in such position as to present the rod in a position ninety degrees from the holder. 7

This hinge feature is provided to prevent danger of damage to thebar 95, should a box be inserted of a different size than that for which the track is set, or if for any reason the box-advancing means should fail, and the bar should come in contact with the box. In

icausing. the bar such an event, the hair would swing open with the head 96 rearwardly compressing the plunger against the springs 101.

With the track again clear of boxes, an op erator has merely to turn the'bar back intopro'perposition. s Thebar 102,0n which the gauge 94 is adjustably mounted, is held in the hinged head 103. of theholder 104 which allows the-bar 102-to swing open. as the carriage 41 returns from the lining to the feeding station, causing the-gauge 94 to run along the laterally directed front ofthe boxu i As soonas the gaugel94 clears the box, a spring pulls the bar 102 backinto posi-- tion, "a suitable inward limit of theghinge again=to project at a ninety degree angle, T

Both the holders 97 and 104 are adjustably mounted on square portions of the bar 98 toward opposite ends thereof making a splitclamp fit with the'bar98, along which they are adaptedto slide. They are clamped-in place by screws 106. i a

' By adjusting the holders in this manner,

*thespacebetween the bar 95 and the bar. 102 can be changed until'the spacebetween the gauges 93 and 94 :is correct for the corner edges at oppositeends of the lining blank winger-6 to fit over the laterally directed front 595 "spectively, .but are left in theisam'e position for all sizes of boxes,such variations" asare necessary being provided for by other means of adjustment.

When the lining blank properly'fits the T paper gauges, any further adjustments will be for thepurpos'e of registering the lining with a box located'in its fixed position at the lining station. Y a For this purpose all three gauges are adjusted as a unit to change the relative location of the whole lining blank with respect to the box, four adjustments being provided, respectively moving the three gauge unit horizontally parallel to the track, horizontally at right angles to the track, angularly inja horizonal plane about a vertical axis, and vertically up and down. A By means of these four adjustments, cruciform lining blanks for any standard box can i be brought into register with the box quickly and easily an d when that result has been achieved all four of the above adjusting mechanisms are locked in place simultaneous'l'y by the tightening of a single nut 108. 13

f'fThe adjustment horizontally parallel to the track is efl'ected by an adjustment'wheel The bar 98, parallel to the track, has lontgitudinal'sliding connection at 110 with the plate 112 adapting the bar to move horizon- ;tallyin either direction parallel to the track Ealong a short range of movement limited by h the-oversize of a vertical hole through the middle of the bar passing the vertical screw 113 thatcarries the nut 108.

An arm 114, rigidly connected at one end to the bar 98, presents its other end between two P lugs 115 that project upwardly from the "plate 112.

" The adjustment wheel 109 is attached to -ascrew 116 which journals freely in the lug bearings 115 and screw-threads through the end of thearm 114 from the bar 98.

"Turning of the wheel 109 can thus move *the bar 98 carrying the gauge unit to a limited extent to and fro parallel to the track guided by its tongue and groove conh nection with the plate 112 beneath it.

To secure the second adjustment the plate 112 is provided with a tongue and groove connection 117 with the upper side of a cir- "cular plate 118 directly beneath the plate 112, the 'tongue and groove connection 117 be- The plate 112 is adjusted in a direction at right angles to the track by rotating a wheel 119 which carries a screw 120 that "lug of the plate 112 and at its inner end threads into a tapped hole in the circular plate 118. 7

It will be evident that as the screw 120 wards or away from the track.

The third or angular adjustment is secured by angular movement of the circular plate 118 about the vertical screw 113.

.The circular plate 118 has an axial bore snugly fitting the vertical screw 113 and when the nut 108 is released, the circular plate 118 is free to turn about the screw 113, causinga similar angular movement in all the parts above it which are mounted on it. The angular movement is supplied by a wheel 122 and a screw 123, the screw carrying the wheeland journaling freely in bearings in a casting 124. -'-Thecircular plate 118 carries an arcuate threaded block 125 which projects downwardly into an upwardly directed arcuate groove. in the top of the casting 124, where 05 it makes threaded engagement with the screw tweenthe plates 112 and 118 extending at journals at 121 in a downwardly projectingis revolved, the plate 112 will be driven to 122, thereby adapting; rotation ofthe screw to angularly turn the circular-plate.

The principal purpose of the angular adjustment. is to bring the wing 48 of the lined on it are moved up or down.

A projection 129 of the casting 126 is screwed fast to an upwardly extending wing 130 (Figure 1) of the slide 71, slidably guided in a suitable recess 131 out in theunder side of the table 132.. i

' The upwardly extending Wing 130 passes through the table in a long slot provided forgo that purpose.

. As already explained, the box-advancing mechanism is also reciprocated by the slide 71 through its connection with the fork 70.

The slide 71 itself is reciprocated by a conmeeting rod. 133 (Figure 1) attached to the lever 133, mounted in a suitable bearing carried by a cross member 134 of the frame.

. The lever133 isxprovided witharoller 133 to engage a groove in the cam 135,100

mounted on the main cam shaft.

The composite box form 42 (Figures 1 and 10 to 13)- that places-the linings in the boxes is reciprocated vertically by cooperating plungers 137 and 138, downwardly into and upwardlyout of the-successive boxes when they are located at the lining station.

The form includes a central casting 139 and composite plate members 140,' the plate members moving outwardly against the box 1 *sides after the block 139 has cometo rest upon the bottom of a box, having carried the lining blank ahead of it to the bottom of the The block 139-is carried upon the lower end of the plunger 137 with'whi'ch it makes a vertical slidable connection, the lower end of the plunger making a sliding fit in a central vertical recess 141 of the block and normally supporting theblock upon opposite lac ends of a horizontal pin 142. Vertical slots 143' in vertical guideway portions of the block permit downward movementof the lower end of the plunger'into therecess of the block after the block comes to rest on 12 the bottom of a box.

The block is spring pressed downwardly with respect to the plunger by springs 144 and 145 which are compressed between opposing upwardly and downwardly directed surfaces of the block and plunger respectively.

The composite plates are supported near their lower edges by shoes 140 which are adapted to slide inwardly and outwardly upon suitable plate'bearings 1.39 fastened to the bottom of the block 139, being posi- 'tioned at the bottom inwardly and outward- 1y by diagonal upwardly and inwardly sloping links 146 to a bar'147 that is rigidly fastened to the bottom of the plunger 137,

and positioned at the top inwardly and out wardly by diagonal upwardly and inwardly sloping links 148 to the plunger 1'38. 1

Each of the four composite plates includes an inner and an outer plate, the outer plate 50 being recessed to receive a narrow pad 51 of sponge rubber, the pad normally protruding beyond the face of the plate.

When the plates 50 are expanded against the box sides, the sponge rubber pad 51 is compressed until its outer face coincides with the plane of the outer plates, offering resilient outward pressure sides. v

Only narrow rubber pads at the top edges of the outer plates 50 are required, to correspond with the stencil glued area of the lining blank.

The same box form can be used for all against the box ordinary boxes, the difierences in box sizes being taken care :of by furnishing sets of outer plates 50 of varying thicknesses.

Longer boxes require thicker end plates,

and wider boxes require thicker side plates. The inner plate members include inwardly extending lugs 150 that pivotally connect at the bottom to the shoes 140 and at the top to the lower ends of the links 1.48, the shoes and links operatinq in suitable slots of the central casting 139.

The form enters the box in contracted position, and upon reaching the box bottom,

the lower edges of the outer plates 50 are expanded into the four lower corners of the box by the continued downward movement of the plunger 137 after the central block 139 comes to rest on the bottom of the box.

During this operation, the upper edges of the outer plates carrying the sponge rubber pads. are kept in contracted position,

"leaving the four upwardly projecting wings of the lining blank adjacent the box walls f ee to yield downwardly as the lower edges of the plates 50 expand into the lowercorners of the box, untilthe lining blank has been folded sharply into the corners by the bottom edges lof the expanded'plates.

Sharp corners are desirable, since boxes are generally made closely to fit the articles they are intended to contain.

VV -th the lower edges-of the outer plates 50 remaining in expanded position, holding the blank in the box corners, the upper edges of the-plates are then expanded, that is moved outwardly, into engagement with the inside walls of the box, the sponge rubber pads furnishing resilient outward pressure against the box walls and causing adherence of the stencil glued portions of the lining lank to the box sides.

Subsequently the upper edges of the plates leaving the box free to stand on the track as the form is upwardly withdrawn from it.

It willbe seen that'two separate and distinct expanding motions are'provided,first the lower, and thenthe upper.

It is evident that when the plunger 13'! an the casting 139 are reciprocated as a unit, the

six shoes 140'. remain stationary with respect to the plunger and central casting-until the casting 139 comes to rest on a box bottom, after which further downward movement of the plunger 137 causes the plunger to enter further into the recess 141 of the casting 139 and therebydriving the six slides 140' outwardly through the connections outlined above,ex1i)anding the lower edges of the four plates 50. v

Subsequent upward movement of the plunger at first serves to retract the sixshoes to their former inward position, the casting 139 being prevented from following the initial upward movementof the plunger by the act-ion of the springs 144 and 145 as well as by its own weight.

When the slides are completely retracted and the pin 142 has reached the upward limit of the slots 143, continued upward movement of the plunger 137 raises the casting 139 and all dependent parts. t p

Two purposes are thus served by the plunger 137, that of reciprocating the form, and that of expanding and contracting the lower edges of the plates. 1 V

The plunger 137 is reciprocated by a link 151 (Figure 1 a lever 151 and an adjustable connecting rod 152attached to a cam lever 153, one end of which is mounted by comprisesa head portion of the plunger 138.

This includes rods 38 adapted to slide in recesses in opposite sides of the main plunger .137. -The rods;138 extend somewhat above the upper end of the main plunger 137 (Figure 1) where they are connected together, and are driven by a connecting block-.158, link 159, lever 160, connecting rod 161, cam lever are contracted first, and then the lower edges,

162 and cam 163 located on the main cam shaft 40.

The plungers 137 and 138 reciprocate as a unit during the greater part of each cycle.

The reinforcing mechanism' operative at station 35 is used when it is desired to reinforce the box hingesby extending the rearward wing 48 of the lining up on to the edge of the lid and then only. The rearward wing is then made about an inch longer than when the hinge reinforcement is not desired.

When the form has completed its lining operation at the lining station 34, (Figures 3 and 4) the upward extension 53 of the wing 48 of a lining is left standing upright from the inside of the rear box wall.

The subsequent cycle of the machine advances the box to the reinforcing station 35 where the upstanding projection 53 of the paper blank is turned over. the top of the rear box wall on to the inside of the box lid.

' The frame 165 (Figures 4 to 6) is attached to the table and is horizontally inwardly flanged at 166 to support the box lids as the boxes are advanced along the track.

Two upstanding arms 167 support aliued bearings 168 to carry a cross hub and shaft portion 169 of a rocker 170, at one end of which is cast a block 171.

The opposite ends of the block 171 are provided with grooves diagonally upward to receive two upwardly projecting supporting lugs 172 of a member 173 that carries the ninety degree angle pad 56 that is in position to engage the turned'flap and is desirably faced with sponge rubber.

The member 173 carrying the angle pad is fastened adjustably to the block 171 of the rocker by means of the lugs 172 that fit adjustably in side grooves of the block where they are fastened in any suitable way. I

I pivotally support similar levers 175 in bracket bearings 176 at the endsof the member 17 3 and mount a rubber covered roller 54 between bearings on the lower ends of the levers 175."

During a reciprocation of the rocker the roller 54 and angle pad 56 movearcuately downwardly to successively engage the'flap,

the roller coming down on the inner corner 178 of the box on the unglued side of the flap.

The box is located in its proper position by the box locators 45.

I guide the roller 54 outwardly over the top of the rear box wall by means of outwardly extending arms 179 from the levers and by cooperating stationary pins 180 in suitable brackets 181.

As the roller descends, the arms 179 maintain contact with the pins 180 until the roller begins to roll outwardly from the corner 178 after which during the remainder of the down stroke of the pad member the arms travel upwardly from the pins.

The arms 179 and pins 180 cooperate in registering the roller with the inner corner of .the box and in then insuring that the roller move upwardly and outwardly rather than inwardly and downwardly.

The roller 54 having creased the paper over the top edge of the rear box wall, rolls the paper outwardly on to thelid and continues outwardly to a position well beyond the paper reinforcing winginorder to be out of the way of the rubber-faced angle pad, which registers with the corner 178 pressing the turned flap to place.

The rubber pad furnishes resilient pressure outward against the rear box wall, and

resilient pressure downward against the top of the rear box wall and the adjacent inner face of the open lid, pressing the paper, previously glued, firmly into place there.

The rocker 170 is reciprocated, through the connecting rod 182 (Figure 1) by the cam 183 on the main cam shaft. 7

A spring 184 is provided to insure the return of the-lever to its initial position,per-

mitting the boxes to move without interference along the track.

The movements of the different parts may be best understood by reference to Figure 21, in which the different curves show the positions of the different parts with respect to the angular position of the main camshaft,

the length of the abscissae corresponding to one complete revolution, 360, of the shaft.

7 The cycle begins with the clutch release Whi('l1 takes place at the point 186 by the depression of the treadle 28 after the box has been placed in position upon the track back ofthe transfer lug 43 and the paper has been placed upon the gaugesabove the box. The lining blank rests on the top of the box with the gauges fitting in three of the corner spaces between the four flaps and the lid flap 48 is supported upon a bar 44 just above the lid. This bar is necessary if there is a lid but may optionally be omitted if the box has no lid.

The paper gauges and transfer lugs move inwardly between the points 188 and 189, the box lining blank and gauges moving as a unit from the feed position to the lining position.

, Before the box has reached the lining position the box locator has made a major portion of its closure stroke, beginning to close at the point 190 and having inwardly advanced the rearward lugs 80 before the gauges and transfer mechanism come to rest at the lining position to overlap the forward end of the box so that the box is unable to of the locators.

. Desirably the complete closure of the box locators which takes place at the point 191 should be a little later than that at which the gauges come to rest in order toprovide time for exactly registering the box with respect to the locators before the locators clamp the box.

The main plunger begins to move downwardly at the point 192 before the box and lining blank have been positioned beneath the plunger and engages the paper blank, pushing it down into the box between the points 189 and 193.

The lugs as, 13 and 43 that have simultaneously advanced three boxes, an unlined box from the position to lining position, a lined box from the lining position to the reinforcing position and a finished box from the 15 reinforcing position to discharge, move downward between the points 191 and 195 starting downward as soon as the box locators have properly taken hold of the box and after having moved. downward far enough to clear the bottoms of advanced boxes return respectively to the positions 33, 34 and 35, moving upward at these positions between the points 196 and 197.

The main block 139 at the lower end of the plunger 137 of the form 12 comes to rest upon the bottom of a box, pressing a blank down on the bottom at the point 193 and the plunger 13'? continues downwardly between the points 193 and 198 to expand the lower edges of the plates into the bottom corners of the box. The plunger 137 comes to rest at the point 198 and the plunger 138 continues downwardly to the point 199, the outward expansion of the upper edges of the plates 50 taking place between the points 198 and 199 during which the plunger 137 is at rest at its low position. The plunger 138, continues to move downwardly to force the upper edges of the plates outwardly, the plunger 138 coming to rest at the point 199.

The paper gauges start back toward the feed position at the point 200 having returned to their initial position at the feeding station at the point 201.

The plunger 138 begins to move upwardly at the point 202 and has completed the contracting movement of the plates 50 at the point 203 at which point the plunger 137 begins to move up as a unit with the plunger 138.

The contraction of the bottom of the edges of the plates 50 take place between the points 203 and 20 1 after which the casting 139 and plungers 137 and 138 continue to move upwardly to the end of the cycle.

The box locators begin to open at the point 205 after the main plunger has lifted the form 42 clear of the boxes, continuing to open to the end of the cycle and leaving the box standing free on the track, with a trans fer lug 43 now positioned back of the box ready to carry the box onward to the reinforcing mechanism.

The box is carried to the reinforcing mechanism, that is from the station 3 1 to the station 35 between the points 188 and 189 of the next cycle during which a new box is brought to the lining station.

The rocker 170 carrying the roller 177 and angle pad 174 moves the roller and pad downwardlybetween the points 206 and 207, the roller engaging the inner edge of the box back of the upward extension" of the blank, creasing the blank over the edge and being guided inwardly over the top of the box and the edge of the lid by cooperating action of he arms 17 9 and pins 180, the angle pad enthe turned down reinforcement flap after the roller is out of the way as seen in Figure 7.

The return movement of the reinforcement rocker takes place between the points 208 and 209 of the next cycle, the lug 43 being again positioned back of the reinforced box at'the point 197 ready to expel the box in the next cycle between the points 188 and 189.
